Title (EN) METHOD AND DEVICE FOR SUPPORTING CATALYST GAUZES IN AN AMMONIA OXIDATION BURNER
(FR) PROCEDE ET DISPOSITIF DE MAINTIEN DE GAZES CATALYTIQUES DANS UN DANS UN BRULEUR D'OXYDATION PAR L'AMMONIAC
Abstract: front page image
(EN)The invention comprise a support system for catalyst gauzes in an ammonia oxidation burner and a method of reducing movement of particulate ceramic material due to thermal dilatation. The catalyst gauzes (1) and possibly support screens (2) are being supported by ceramic fillings contained in a burner basket with metal walls and a perforated bottom plate. A 'wave breaker' (9, 11) is fixed to the metal wall (4) and/or the outer part/periphery of the bottom plate (5).
(FR)L'invention concerne un système de maintien utilisé dans un brûleur d'oxydation par l'ammoniac et un procédé permettant de réduire le mouvement d'un matériau céramique particulaire du à la dilatation thermique. Les gazes catalytiques (1) et éventuellement les tamis de maintien (2) sont maintenus par des charges de céramique contenues dans un panier de brûleur avec parois métalliques et plaque de fond perforée. Un 'brise-ondes' (9, 11) est fixé à la paroi métallique (4) et/ou à la partie extérieure/périphérie de la plaque de fond (5).
